Perfectly good tenant house not allowing tenants

so i've been building up a colony planet, and wanted to build some rather big houses in one area. However, when i put up tenant deeds in the 3 houses i've built and decorated they keep saying the houses are unfit for tenants. i've triple checked every house for holes in the walls and roof and background, and can't find any. all houses are well lit and have doors (i made sure not to use doors from mods in case that was the problem), and yet i still can't get any tenants to move in (i just get the red X). is there a house size limit? or some other necessity for tenants to move in?

 

Its probably window lattice doesnt count as having covered the window opening, if you have any.

 

here are screenshots of the houses (did my best to capture all of them)

 

i'll give it a shot.
it's strange, lattice windows have always been fine in the past.... in fact almost all of these materials have been fine in the past. wonder which it is that is breaking it

edit: i replaced the lattice windows but it still isn't working (on the glitch tower, haven't tried the other houses yet)

 

that could be it, but i've had other hosues with seperate rooms.
.......
could it be because there's a terraformer nearby?

 

i've replaced the background blocks that i dont usually use, but it still isn't working

 

The problem that I can see is a lack of doors. also if a room is too large it will not count as being suitable, but I am sure that the blocks you are using are fine. I actually haven't found a block that isn't usable as a background.

 

it's odd because i've had really big houses before, but i guess i never actually passed the limit? guess i'll have to resize some of my houses...

update: i removed the top floor of the offending homes and it worked just fine! thanks for your help everyone
